These are simply scanned documents of my work from when I first did the problems. I'll try to be neater with my work for the 2nd week and beyond. If you want to, you can upload your own solutions as well; be sure to sign your name next to it like I did.
You'll notice that all the TA's work problems differently. I've provided my solutions to offer you a different perspective.

Jan 26, 2010: -Originally, the question used the symbol sigma instead of eta for the charge density so that's what I've used in this solution. Also, before the TA messed up doing the problem, they had used 'r' instead of rho to describe how the charge density varies on the surface of the disk. i.e. sigma=sigma_0*r^2, instead of eta=eta_0*rho^2. -Manu

February 9, 2010: - Scroll to page 3 for example problem solution. This solution is very well written and is worth your time to look at. -Manu
